Description

Information processing method, device and readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method, an information processing device, and a readable storage medium.

Background

In order to solve the problems of coverage, delay and capacity of uplink transmission in a TDD (Time domain duplex, time division duplex) mode, a technology of non-overlapping sub-band full duplex (non-overlapping sub-band full duplex) is studied, that is, frequency domain resources are divided into a plurality of sub-bands and are not overlapped with each other, and uplink and downlink frequency domain resources are located in different sub-bands respectively, hereinafter, referred to as full duplex.

In the prior art, the time-frequency domain transmission resources of the repeated transmission of the terminal are configured at one time by DCI (Downlink Control Information ). However, in practical applications, there is a possibility that the retransmission is interrupted due to the unavailability of the remaining retransmission resources or the network wants to change the size/position of the uplink and downlink resources corresponding to the remaining retransmission times. This may occur, for example, when the network switches from a static/dynamic TDD mode to a full duplex mode, or when the network switches from a full duplex mode to a static/dynamic TDD mode, or when BWP (Bandwidth part) switches.

Therefore, how to avoid the retransmission interruption due to the unavailability of the remaining retransmission resources before the number of retransmissions is performed is a technical problem to be considered.

Detailed Description

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The embodiment of the application provides an information processing method and device, which are used for improving transmission efficiency and reducing transmission delay.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided in an embodiment of the present application, as shown in fig. 1, including the following steps:

step 101, the terminal performs repeated transmission of the target TB according to the first DCI.

Wherein the target TB may be an arbitrary TB. In practical application, the network schedules a new transmission or HARQ retransmission of the target TB through the first DCI, and may configure the repetition number of the target TB through the first DCI or RRC (Radio Resource Control ) signaling, so that the terminal may receive or transmit the target TB according to the scheduling of the base station. Therefore, the first DCI is a DCI for first scheduling a new transmission or HARQ retransmission of the target TB, and may be implemented using an existing arbitrary DCI format.

Step 102, the terminal receives the second DCI.

The second DCI is DCI for scheduling an HARQ process where the target TB is located. The second DCI is received without performing all repeated transmission of the target TB. Thus, the second DCI is DCI that the terminal receives again in performing a repeated transmission of a new transmission or HARQ retransmission of the target TB scheduled by the first DCI. The formats of the second DCI and the first DCI may be the same or different.

Step 103, the terminal determines the remaining repeated transmission resources of the target TB according to the second DCI based on the effective start time of the second DCI.

In the embodiment of the present application, the remaining retransmission is a retransmission that is not performed by the terminal at the effective start time of the second DCI according to the configured number of retransmissions of the target TB. The number of repeated transmissions of the target TB may be configured by the first DCI, or may be configured by RRC signaling, or may be configured by other manners. The validation start time of the second DCI may be indicated by the second DCI. The remaining retransmission resources refer to resources for performing the remaining retransmission.

In the embodiment of the application, the terminal judges the effective starting time of the second DCI to determine whether to determine the residual repeated transmission resources of the target TB according to the second DCI.

In this step, whether remaining retransmission resources of the target TB are determined according to the second DCI may be determined in the following ways.

(1) The terminal obtains the effective starting time of the second DCI; and if the effective starting time of the second DCI is in the repeated transmission process of the target TB, the terminal determines the residual repeated transmission resources of the target TB according to the second DCI.

Specifically, the effective start time of the second DCI is located in a time slot where a target time is located, or the effective start time of the second DCI is located in a kth time slot after the time slot where the target time is located; the target time is the time when the terminal receives the second DCI; k is an integer greater than 0. k is timing information indicated in the second DCI. When the second DCI is used for scheduling the PDSCH, the value of k is k0 indicated in the second DCI; and when the second DCI is used for scheduling the PUSCH, the value of k is k2 indicated in the second DCI.

The "the effective start time of the second DCI is located in the retransmission process of the target TB" may be understood that the effective start time of the second DCI is located in a start slot (slot) or symbol (symbol) of the last retransmission of the target TB, or the effective start time of the second DCI is located before the start slot or symbol of the last retransmission of the target TB. That is, at the effective start time of the second DCI, the terminal still has not performed more than or equal to 1 repeated transmission.

In this case, for the target TB, if the terminal receives the second DCI corresponding to the HARQ process where the target TB is located in the case that the number N of repetitions configured by the base station is not performed, if the valid start time of the second DCI is located in the repetition transmission process of the target TB block in the HARQ process, the terminal determines resources for performing the remaining repetition transmission according to the determination indicated by the second DCI, and performs the remaining repetition transmission according to the scheduling of the second DCI.

That is, the base station issues the second DCI for updating the resource configuration of the remaining number of repeated transmissions in the process of performing repeated transmission by the terminal. And if the target TB block in the process corresponding to the second DCI has residual repetition times which are not executed according to the time position of the received second DCI, the terminal executes the residual repetition transmission times according to the resources configured by the received second DCI.

(2) And the terminal acquires the effective starting time of the second DCI. And if the effective starting time of the second DCI is in the repeated transmission process of the target TB and the target field of the second DCI indicates retransmission or reconfiguration, the terminal determines the residual repeated transmission resources of the target TB according to the second DCI.

The meaning and the acquisition manner of the effective start time of the second DCI are the same as those described in the foregoing embodiments. The meaning of "the effective start time of the second DCI is located in the repeated transmission of the target TB" is the same as that described in the previous embodiment. The target field includes an NDI field or a reconfiguration indication field, where the NDI field is used to indicate retransmission and the reconfiguration field is used to indicate reconfiguration.

For example, the base station schedules a new transmission or HARQ retransmission of the target TB through the first DCI (the new transmission or HARQ retransmission is indicated through an NDI field in the first DCI), and configures the number of repetitions of the target TB to be N. And the terminal receives or transmits the target TB according to the scheduling of the base station. For the target TB, if the terminal receives a second DCI for the HARQ process where the target TB is located and NDI in the second DCI indicates retransmission under the condition that the repetition number N is not performed, the terminal determines resources for performing remaining repeated transmission according to the indication of the second DCI and performs remaining repeated transmission according to scheduling of the second DCI.

(3) And the terminal acquires the effective starting time of the second DCI. The terminal determines remaining repeated transmission resources of the target TB according to the second DCI when the following three conditions are simultaneously satisfied:

and (3) a third condition: and the effective starting time of the second DCI, the number of the completed repeated transmission times of the target TB is larger than or equal to a first threshold value, or the ratio of the number of the completed repeated transmission times of the target TB to the total repeated transmission times of the target TB is larger than or equal to a second threshold value.

The meaning and the acquisition manner of the effective start time of the second DCI are the same as those described in the foregoing embodiments. The meaning of "the effective start time of the second DCI is located in the repeated transmission of the target TB" is the same as that described in the previous embodiment. The target field includes an NDI field or a reconfiguration indication field. The first threshold and the second threshold may be set according to actual needs, and may be predefined, DCI notification, or configured through RRC signaling, etc.

In the case that the first and second conditions are satisfied, in the third condition, if the number of completed retransmissions of the target TB is smaller than the first threshold, or the ratio of the number of completed retransmissions of the target TB to the total number of retransmissions of the target TB is smaller than the second threshold, the terminal may perform HARQ retransmission of the target TB or new transmission of the next TB.

For example, the base station schedules a new transmission or HARQ retransmission of the target TB through the first DCI (the new transmission or HARQ retransmission is indicated through an NDI field in the first DCI), and configures the number of repetitions of the target TB to be N. And the terminal receives or transmits the target TB according to the scheduling of the base station. For the target TB, if the terminal receives a second DCI for an HARQ process where the target TB is located in the case that the repetition number N is not performed, where NDI in the second DCI indicates retransmission, and a ratio of the number of completed repeated transmissions to the total number of repeated transmissions of the target TB is greater than or equal to a second threshold, the terminal determines resources for performing remaining repeated transmissions according to the determined resources indicated by the second DCI, and performs remaining repeated transmissions according to scheduling of the second DCI; otherwise, the terminal executes HARQ retransmission of the target TB or new transmission of the next TB.

Step 104, the terminal executes the residual repeated transmission of the target TB according to the residual repeated transmission resources of the target TB.

In the embodiment of the present application, the remaining repeated transmissions of the target TB include all the remaining repeated transmissions corresponding to the remaining repeated transmission times of the target TB, or the remaining repeated transmissions of the target TB include the repeated transmissions corresponding to the partial repeated transmission times of the remaining repeated transmission times of the target TB.

The remaining repeated transmission resources may be determined according to the second DCI. Specifically, the second DCI may include a time-domain and/or frequency-domain resource indication field, and the terminal may determine the remaining retransmission resources according to the field in the second DCI.

In the embodiment of the present application, the terminal may determine the remaining retransmission resources of the target TB according to the second DCI, and perform the remaining retransmission of the target TB according to the remaining retransmission resources of the target TB. Therefore, by utilizing the scheme of the embodiment of the application, the residual repeated transmission resources of the target TB can be configured, so that the smooth execution of repeated transmission or the reconfiguration of the transmission resources can be ensured.

Referring to fig. 2, fig. 2 is a flowchart of an information processing method according to an embodiment of the present application, as shown in fig. 2, including the following steps:

Step 201, the network device sends a first DCI to the terminal for scheduling repeated transmission of the target transport block TB.

Step 202, the network device determines a second DCI. The second DCI is DCI for scheduling an HARQ process where a target TB is located, and is configured to instruct the terminal to determine, based on the second DCI, a remaining repeated transmission resource of the target TB according to the second DCI based on an effective start time of the second DCI.

In this step, the second DCI includes a validation start time of the second DCI; the effective start time of the second DCI is located in a repeated transmission process of the target TB. The effective start time of the second DCI is located in a repeated transmission process of the target TB, including: the effective start time of the second DCI is located in the start slot or symbol of the last retransmission of the target TB, or the effective start time of the second DCI is located before the start slot or symbol of the last retransmission of the target TB.

Optionally, the second DCI further includes a target field; the target field indicates a retransmission or reconfiguration. The target field includes an NDI field or a reconfiguration indication field, where the NDI field is used to indicate retransmission and the reconfiguration field is used to indicate reconfiguration.

Optionally, at the effective start time of the second DCI, the number of completed retransmissions of the target TB is greater than or equal to a first threshold, or the ratio of the number of completed retransmissions of the target TB to the total number of retransmissions of the target TB is greater than or equal to a second threshold. Wherein the first threshold and the second threshold may be set as desired.

Wherein the second DCI includes an effective start time of the second DCI; the effective starting time of the second DCI is a time slot in which a target time is located, or the effective starting time of the second DCI is a kth time slot after the time slot in which the target time is located; the target time is the time when the terminal receives the second DCI; k is an integer greater than 0.

When the second DCI is used for scheduling PDSCH, the value of k is k0 indicated in the second DCI; and when the second DCI is used for scheduling the PUSCH, the value of k is k2 indicated in the second DCI.

Meanwhile, the second DCI may further indicate resources used to perform the remaining repeated transmission. Wherein the meaning of the remaining retransmission and the remaining retransmission resources may be referred to the description of the foregoing embodiments.

Step 203, the network device sends the second DCI to the terminal.

Step 204, the network device receives or transmits the target TB according to the remaining repeated transmission resources determined by the second DCI.

In the embodiment of the present application, the remaining retransmission is a retransmission that is not performed by the terminal at the effective start time of the second DCI according to the configured number of retransmissions of the target TB.

In the embodiment of the present application, the network device may instruct the terminal to determine the remaining retransmission resources of the target TB according to the second DCI, and perform the remaining retransmission of the target TB according to the remaining retransmission resources of the target TB. Therefore, by utilizing the scheme of the embodiment of the application, the residual repeated transmission resources of the target TB can be configured, so that the smooth execution of repeated transmission or the reconfiguration of the transmission resources can be ensured.

In the embodiment of the application, for the DCI scheduling of a certain HARQ process, if the effective starting time is in the repeated transmission process of the TB block in the HARQ process, the terminal determines the transmission resource corresponding to the incomplete repeated times when the DCI is effective according to the DCI. Hereinafter, the implementation procedure of the information processing method of the present application will be described in connection with different embodiments.

In one embodiment of the present application, the network or the base station schedules a new transmission of the TB through the first DCI, i.e. the NDI field in the first DCI indicates the new transmission, the corresponding HARQ process number (HARQ process number) field indicates 0, and configures the number of repeated transmissions of the TB to be 8 through RRC signaling or the first DCI. And the terminal repeatedly receives or transmits the TB according to the scheduling of the network or the base station. For the new transmission of the TB, if the terminal receives the second DCI when the repeated transmission times are only executed for 4 times, the HARQ process number field of the second DCI indicates 0, and the effective starting time of the second DCI is before the 5 th repeated transmission, the terminal executes the rest 4 repeated transmissions according to the second DCI; otherwise, the terminal transmits the TB according to the configuration information in the first DCI.

The first DCI and the second DCI may have the same or different DCI formats, where the first DCI is first scheduling a new transmission of a TB, and the second DCI is DCI received by the terminal again in a repeated transmission process of executing the new transmission of the TB. Both the first DCI and the second DCI may be implemented using any DCI format in the prior art.

If the network or the base station schedules the HARQ retransmission of the TB through the first DCI, that is, the NDI field in the first DCI indicates the retransmission, the processing manner of the terminal is the same as the principle of the processing manner when the first DCI schedules the new transmission of the TB.

The effective start time of the second DCI may be a time slot where the second DCI is received, for example slot n, or a kth time slot after slot n. Alternatively, k may be predefined, configured in the second DCI or the first DCI (for PDSCH, k is indicated in DCI as k0; for PUSCH, k is indicated in DCI as k 2), or configured by RRC signaling.

Optionally, the number of repeated transmissions in effect of the second DCI may be all the remaining number of repeated transmissions corresponding to the time when the second DCI is received, or may be a part of the remaining number of repeated transmissions, for example, the remaining 4 times of repeated transmissions are not transmitted at the time when the second DCI is received, and then the number of repeated transmissions in effect of the second DCI may be all the remaining 4 times, or may be the remaining last 3 times of repeated transmissions. Based on the second DCI scheduling information, 1 repetition transmission is reserved in the middle as a transition period.

In one embodiment of the present application, the network or the base station schedules a new transmission of the TB through the first DCI, i.e. the NDI field in the first DCI indicates the new transmission, the corresponding HARQ process number field indicates 1, and the number of repeated transmissions of the TB is configured to be 8 through RRC signaling or DCI. And the terminal repeatedly receives or transmits the TB according to the scheduling of the network or the base station. For the new transmission of the TB, if the terminal receives the second DCI when the repeated transmission times are only executed for 6 times, a HARQ process number field of the second DCI schedule indicates 1, and an NDI field indicates HARQ retransmission before executing the 7 th repeated transmission, the terminal executes the remaining 2 repeated transmissions according to the schedule of the second DCI; otherwise, the terminal transmits the TB according to the configuration information in the first DCI.

The first DCI and the second DCI may be the same or different DCI formats, where the first DCI is first scheduling a new transmission of a TB, and the second DCI is DCI received by the terminal again in a repeated transmission process of executing the new transmission of the TB. Both the first DCI and the second DCI may be implemented using any DCI format in the prior art.

Optionally, the number of repeated transmissions in effect of the second DCI may be all remaining repeated transmission numbers corresponding to the time when the second DCI is received, or may be a part of the remaining repeated transmission numbers, for example, when the second DCI is received, there are 2 remaining repetitions without transmission, and the number of repeated transmissions in effect of the second DCI may be all remaining 2, or may be that the last remaining 1 repetition is based on the second DCI scheduling information, so that 1 repetition transmission may be reserved as a transition period.

In one embodiment of the present application, the network or the base station schedules a new transmission of the TB through the first DCI, i.e. the NDI field in the first DCI indicates the new transmission, the corresponding HARQ process number field indicates 1, and configures the number of repeated transmissions of the TB to be 8 through RRC signaling or DCI, where β is equal to 0.5. And the terminal repeatedly receives or transmits the TB according to the scheduling of the network or the base station. For a new transmission of the TB, if the terminal receives the second DCI when the number of repeated transmissions is only 1, and HARQ process number field of the second DCI schedule indicates 1 and ndi field indicates HARQ retransmission. Since 1/8 is less than 0.5, then the terminal gives up the remaining 7 repeated transmissions, performing HARQ retransmission according to the second DCI schedule; if the terminal receives the second DCI when the number of repeated transmissions is only 5, HARQ process number field of the second DCI schedule indicates 1, and NDI field indicates HARQ retransmission before the 6 th repeated transmission is performed, since 5/8 is greater than 0.5, the terminal performs the remaining 3 repeated transmissions according to the second DCI schedule.

Optionally, the number of repeated transmissions in effect of the second DCI may be all the remaining number of repeated transmissions corresponding to the time when the second DCI is received, or may be a part of the remaining number of repeated transmissions, for example, the remaining 2 times of repeated transmissions are not transmitted when the second DCI is received, and the number of repeated transmissions in effect of the second DCI may be all the remaining 2 times, or may be the remaining last 1 time of repeated transmissions based on the second DCI scheduling information, so that 1 repeated transmission is reserved in the middle as a transition period.

As can be seen from the above embodiments, in the embodiments of the present application, based on the existing DCI format, configuring the transmission resources of the remaining retransmission times in the TB retransmission process can solve the retransmission interruption caused by the unavailability of the remaining retransmission resources due to the duplex mode switching or the BWP switching. In addition, through the technical scheme of the embodiment of the application, the size of the resources before/after switching can be changed, so that abundant network resources before and after switching are fully utilized, the transmission efficiency is improved, and the transmission delay is reduced.

In addition, for some scenarios, such as duplex mode switching (switching between TDD and full duplex), BWP switching, and the like, since the network or the base station can reconfigure the resources of the remaining repeated transmissions after switching, the resources can be flexibly configured before switching without being limited by whether the resources are available after switching, thereby reducing the complexity of the network or the base station scheduling.
